Graduate Degrees in Astrophysical & Planetary Sciences

Uniquely combining astrophysics and planetary science, the Department of Astrophysical and Planetary Sciences provides students with a unified view of space sciences; the solar system and comparative planetology; stellar and galactic astronomy; and cosmology.

Graduate students are given hands-on experience with telescopes, optics, instrumentation, and computer image processing and modeling. Our PhD program allows students to practice teaching, assist in cutting-edge research and begin to take part in the larger professional astrophysics community.

Degree Options & Application Requirements

Astrophysical & Planetary Sciences

Doctor of Philosophy

A minimum of 37 credit hours of coursework (including 4 credit hours of graduate seminars) in courses numbered 5000 or above is required; however, the overall emphasis is on independent study and research. A minimum of 30 credit hours of PhD dissertation credit hours is required.
Students in the PhD program are required to remove any deficiencies identified at the preliminary interview; to pass a comprehensive examination composed of writing a research paper based on a semi-independent research project, then an oral exam on that paper and related topics within the field; and to satisfactorily defend the PhD thesis before a baby直播app committee.
The department鈥檚 general astronomy track lends itself to a career in education, science journalism, science policy, information technology, science management or technical work where a graduate degree is not required.
The more math-intensive astrophysics/physics track is intended for students who wish to do research and continue on to graduate work in astronomy or planetary sciences. This track also lends itself well to a career in technical work related to the field.

GRE/GMAT Requirements

The GREs are optional. You should consider taking the GRE and reporting a score to us if you think there is some attribute in your academic performance that the GRE would help offset. As an example, if you felt your GPA was quite low but you got a good score on the GREs, you might use those to argue that your academic preparedness was stronger than reflected by your GPA. Not having a GRE score will in no way negatively affect an application.听

Application Deadlines

Applications are open through Dec. 1. All letters of recommendation must be submitted by Dec. 15 or they might not be evaluated with the rest of your application.
